Hello Guys

If I define this 

\!\(test[\(v\_0\) _, \ \[Gamma]_, \ H_, \ 
      m_] :=
\((\(\(-m\)*H\)\/\[Gamma]\^2*Cosh[ArcSinh[v\_0*\[Gamma]\/H]] - 
        m\/\[Gamma]*ArcSinh[v\_0*\[Gamma]\/H]*v\_0)\)\)

and then try to calculate test[14,500,100,80] nothing happens!

What could be the problem?


Thanks!
